Meralco Solar Rebate vs Net Metering: Which Program Saves Philippine Homeowners More Money in 2026?

Every solar installer quote comes with the same two names: Meralco solar rebate and net metering Philippines. Two programs. Two paper trails. Zero clarity on which one actually dents your singil sa ilaw. That ends here.

Both are real. Both have value. Neither cancels the other out. But they operate on completely different timelines — and prioritizing the wrong one can quietly add two to three years to your payback period.

Paano Gumagana ang Bawat Program?

The rebate and net metering solve different problems. The rebate helps you on day one. Net metering helps you every month for the next 20-plus years.

Magkano ang Maititipid Mo? Real PHP Numbers

Abstract comparisons don't pay the singil sa ilaw. Here's a concrete scenario drawn from Metro Manila homeowners we see every week.

Meet Roderick — Parañaque, PHP 6,000 average monthly Meralco bill, 5kW solar system at PHP 250,000 all-in. A composite, but the numbers are typical.

With net metering, Roderick's daytime solar generation offsets consumption directly — and every surplus kWh gets credited at PHP 12–14/kWh against his next bill. His monthly payment drops from PHP 6,000 to an estimated PHP 800–1,200. That's PHP 4,800–5,200 back in his pocket every single month.

The Meralco rebate alone? It trims PHP 5,000–15,000 off installation cost. Once. You'd recover that same amount in one to three months of net metering credits. It is not a competition.

"Net metering is the gift that keeps on giving — bawat kWh na hindi mo nagamit, ibabawas sa susunod na singil. The rebate is a one-time thank you; net metering is a recurring salary."

VECO customers in Metro Cebu access the same RA 9513 net metering framework — verify your current per-kWh rate with VECO directly before locking in projections.

Ano ang Dapat Mong Gawin Ngayon?

Three moves. Most of the legwork falls to your installer. Your job is knowing what to demand.

1. 1
   Get a quote and nail down system size. A 3kW system is the practical floor for net metering to make financial sense. Ask your installer explicitly: "Will this system qualify for net metering?" Hesitation is your first warning sign.
2. 2
   Make your installer own the net metering paperwork. Any accredited installer worth hiring manages the Certificate of Compliance, single-line diagram, and DU application. If yours declines, walk. That is a red flag.
3. 3
   Stack the Meralco rebate on top where available. Hindi sila mutually exclusive — the rebate is an installation incentive, net metering is a billing mechanism. Confirm current stacking eligibility with your installer, since program terms update annually.

Mga Tanong na Madalas Itanong (FAQ)

Can I get both the Meralco solar rebate AND net metering at the same time?

Yes, in most cases — they operate independently. The rebate is a one-time installation incentive; net metering is an ongoing billing mechanism. Confirm current stacking eligibility with your installer, as program terms update annually.

How long does net metering approval take in the Philippines?

Typically 2–4 months from application submission to your distribution utility. Delays almost always trace back to incomplete documents, so have your Certificate of Compliance and single-line diagram ready before submitting.

Is the Meralco solar rebate available outside Metro Manila?

No — it applies only within Meralco's franchise area (Metro Manila and portions of Bulacan, Cavite, Laguna, and Rizal). Net metering under RA 9513, however, is available nationwide regardless of your DU.

What happens to unused net metering credits at the end of the year?

Unused credits at the close of the annual settlement period are compensated at the avoided cost rate — essentially cashed out at a lower rate than the retail credit. Right-size your system to offset consumption, not massively over-export.

Do I need a special meter for net metering?

Yes — your DU installs a bidirectional meter that tracks both consumption and export. Meralco handles meter installation as part of the application; your installer should factor the replacement fee into total project cost upfront.
